Description
The present invention proposes a kind of light-beam display method, uses a kind of light-emitting device array of columnar arrangement, with the quantity demonstration measured value of lighting elements.Relate to the demonstration of one or more measured values on same display unit, international Patent classificating number is G01D7/00; G01D 7/02; G01D 7/08.
The display packing that existing light beam display device is adopted all is that the end from light beam is that starting point begins to show.Just the light-emitting component of an end of light beam is defined as less than following franchise or greater than a certain demonstration truth of a matter of last franchise, lights the height of light beam and in fact represent measured value to be greater than or less than the departure that shows the truth of a matter.Represent on the light beam expectation value, on the position of franchise and following franchise a sign respectively is set, compare with it to make things convenient for the user will light terminal point, judge the size of actual measured value and whether overproof.Be under the situation of starting point with the lower end, lighting the height of light beam and represent that measured value is greater than the departure that shows the truth of a matter.When lighting terminal point and do not enter down the franchise sign, the expression measured value is for negative overproof; When lighting terminal point up and down between the franchise sign time, the expression measured value is certified products in tolerance; When lighting terminal point and surpass last franchise sign, the expression measured value is for just overproof.Be to show in the system of starting point with the upper end with above-mentioned opposite.
In public field, the MINITRON electron beam display instrument of U.S. AIR GAGE company, the E4 series light beam display instrument of Italian MARPOSS company all adopts this display packing.Wherein the E4 series of products of MARPOSS company adopt mechanical vernier as the franchise sign; The MINITRON product of U.S. AIR GAGE company then need be provided with the franchise sign by the user pastes mark on the light beam limit way.
The problem that existing light-beam display method exists is that reading and determination methods when positive and negative deviation are inconsistent, have increased the difficulty of user learning and use.The user must be earlier according to lighting the position judgment bias direction of terminal point with respect to expectation value when observing measurement result, again according to lighting terminal point apart from the expectation value or the size of the distance judgement departure of franchise sign up and down.Reading all of the judgement of bias direction and departure must be carried out after demonstration is stable.When overgauge, judge that the criterion of bias direction is " expectation value sign top has or not the light-emitting component of lighting "; When minus deviation, the bias direction criterion has then become " having or not the light-emitting component of not lighting below the expectation value sign ".When reading departure, for overgauge, he need count the quantity of lighting elements above the expectation value sign; For minus deviation, he must change counting again into and light terminal point to the light-emitting component number of not lighting between the expectation value sign.The interpretation process of this complexity makes the people feel to be difficult to grasp sometimes.In addition, when specifically reading measured value, user or count whole lighting elements quantity asks arithmetic sum with showing the truth of a matter again; Perhaps counting is lighted terminal point to expectation value or the lighting elements number between the franchise sign up and down, calculates the algebraic sum with these signs again.Preceding a kind of method is worked as the light-emitting component quantity of lighting and is counted inconvenience more for a long time; The computation process of a kind of method in back is too complicated again.The franchise sign is set outside light-emitting component, observer's inconvenience directly read the departure between measured value and franchise; Simultaneously, also be difficult to and unified reference signal or the alerting signal that machining control is provided of handling of measured value electric signal; In addition, these methods do not have to make full use of the characteristics of light beam intuitive display.
Task of the present invention is to propose a kind of new light-beam display method, overcomes interpretation difficulty and the inconsistent problem of interpretation method that prior art exists.
Light-beam display method of the present invention uses the light-emitting device array of columnar arrangement, with the height indication measurement value of continuity point light post, is provided with the sign of scale and indication Measurement Allowance.Unlike the prior art be: with any one light-emitting component on the light beam is that starting point begins to show, represents a certain expectation value that measured value equals to set with the light-emitting component of lighting this point; With the quantitaes measured value of lighting the light-emitting component that shows the starting point top departure greater than described expectation value; With the quantitaes measured value of lighting the light-emitting component that shows the starting point below departure less than described expectation value; The sign of described indication Measurement Allowance is the light-emitting component of lighting with flashing mode in the light beam (cursor), and this blinking cursor can be located on one or several the non-overlapping light-emitting component that shows any one or both sides of starting point; Described scale is a series of light-emitting components of lighting with visibly different brightness in the light beam, and they are positioned at apart from an integral multiple light-emitting component place that shows starting point 2 or 5.
Enforcement of the present invention need be used by light-emitting device array intelligent cell control, columnar arrangement, and this intelligent cell should lighting separately and extinguish and carry out control each light-emitting component in the array.
The hardware circuit that can satisfy above-mentioned requirements in the prior art is diversified.For example, with one of single chip microcomputer control by m capable * light-emitting device array of n row is exactly a kind of scheme preferably.In such system, be easy to come the current potential height (put 1 or put 0) of each row and column in the control Driver Circuit, and then control lighting or extinguishing of each light-emitting component by method from video data to output port that write.Employing is shorter than the cycle that human eye vision persists the time and writes video data to output port, just can form stable display effect.Light or extinguish some light-emitting component on the light beam according to the requirement of the inventive method, just can implement the present invention easily.
Said video data can be not less than at its number of bits and generate in the storage portions (one or more byte) of light-emitting component number and processing; This storage portions is called the video data buffer zone.A kind of scheme is, by the arrangement in hardware and the wiring, makes the binary digit of each from the low address to the high address in the display buffer, respectively from top to bottom light-emitting component on the corresponding light beam.This scheme can make bit manipulation become easy; But may cause the hardware connection more complicated.Another kind of scheme is to adopt the simplest hardware connection, and makes in the display buffer on the non-conterminous binary digit and light beam light-emitting component from top to bottom set up corresponding relation; But this will make the bit manipulation process become complicated.These two kinds of schemes can be transformed into display packing of the present invention bit manipulation to video data in the buffer zone.When the some binary digit set in the video data (put 0 or put 1), the result who sends to output port can control the light-emitting component of correspondence just and light; Otherwise also can control it extinguishes.
Above-mentioned two kinds of schemes all are to realize easily in the prior art scope.In fact it relate to the technology of hardware decoding or software decoding.The professional is not difficult according to requirement of the present invention, obtains available design proposal by reasoning and deduction.
Certainly, also need handle and send said video data according to the rule of the inventive method regulation.Handle and send video data according to following rule and can realize display packing of the present invention:
1, before some continuous port output function, according to the cursor position data of user input with cursor display position position; Before other continuous port output functions, again it is resetted.If the periodicity of the periodicity of this continuous set output and continuous reset output all persists the time greater than human eye vision, just can form the effect of being lighted by flicker as the light-emitting component of cursor.
2, to be shorter than the cycle that human eye vision persists the time, replace those binary digits of the set and the corresponding scale that resets, thereby form to light the effect of those light-emitting components than low-light level.The scale position is determined according to the demonstration start point data of user's input; They always are positioned at an integral multiple light-emitting component place of distance display starting point 2 or 5.So form a kind of rule that floats with the demonstration start position, further facilitate reading.
3, before each port output function all according to measured value with departure display position position.
Constantly repeat aforesaid operations, just can realize display packing of the present invention.
Compared with prior art, good effect of the present invention is conspicuous:
At first, display packing of the present invention only shows that measured value is greater than or less than the departure of expectation value, and the light-emitting component number of lighting is less, easily counting; Bias direction judges easily with to light direction consistent, even can obtain bias direction information before stable showing; The departure number reading method is also unified: the quantity that all is the direct census lighting elements; The method of asking of actual measured value is is also unified and simplified: departure and expectation value are asked algebraic sum.In addition, unsteady rule of the present invention makes reading convenient.
Secondly, the present invention adopts light-emitting component that flicker lights as the franchise sign, and the convenient user of franchise sign who is located at outside the light-emitting component than prior art judges and reading.In addition, if necessary, this overproof signal is easy to be used to report to the police or as the reference signal of machining control.A plurality of franchise signs (cursor) are set are used for different quality control standards.
At last, positive and negative overproof judgement all utilizes unified criterion: light light beam and whether surpassed some franchise signs.Light and exist point of scintillation just to illustrate that lighting light beam has surpassed the franchise sign, can conclude in view of the above that measuring object is overproof in the light beam.

Below contrast embodiment of description of drawings.According to the description of claims and this instructions, the present invention is easy to implement.
As previously mentioned, can adopt a kind of by monolithic processor controlled scanning display circuit.It is made up of 100 arrangement pillared light emitting diode [2] arrays [1], from top to bottom with 0 to 99(63H) numbering.By the arrangement in Interface design and the wiring, make 100 binary digits that adhere to 13 bytes in this corresponding respectively display buffer of 100 light emitting diodes by low address to high address separately.Realize display packing of the present invention by bit manipulation to these 13 byte video datas.Certainly, also can adopt the hardware connection scheme of simplifying as far as possible, and realize the corresponding relation of display buffer and light-emitting component by software decoding.As above-mentioned, this scheme can relate to the complicated coding and the decoded operation of trouble.This scheme is not described in detail at this.
Processing and transmission with a dual cycle control video data.
Wherein outer circulation is responsible for reading displayed starting point and cursor position data, controls the set of cursor demonstration position and is resetted, reads measured value and set departure demonstration position; In circulation carry out the port output function, and before data output with every set of corresponding scale or reset.
Define the number of times that two counters are controlled cursor and scale display position position respectively and resetted and export.Change position, scale position and the number of times ratio of the output that resets, just can change the brightness of scale.Utilize this technology can realize the effect that the scale low-light level shows easily, and can adjust scale easily and light the contrast of light beam brightness.Change cursor display position position and the number of times ratio of the output that resets, then can change the dutycycle of cursor flicker.This helps to make display packing of the present invention to reach better effect.To be described in detail in the back this.
The span of measured value is defined in 0 to 99(63H) between.The measured value that exceeds this scope be should give shielding.When receiving measured value, program just will be worth and show each the binary digit set between the starting point, and everybody resets for all the other.So just, finished the setting of departure demonstration position.This data are sent to output port, just can realize by the feature that a bit begins arbitrarily on the light beam to different direction lighting elements.Because human eye is relatively more responsive to moving target, this feature is very beneficial for the information that the user obtains bias direction.
The lighting and extinguish and to adopt following technology of scale: in memory, open up a data field isometric again, be used to deposit the scale position that calculates according to this demonstration starting point with the display buffer.When the user imported the demonstration starting point, just with the binary digit set of corresponding scale in this data field, everybody resetted for other.When needs extinguish scale, with this data field with display buffer data logical, make corresponding scale value in the video data everybody reset.When lighting scale, skip by needs this operation.Can realize that so just scale is only just lighted when measured value is arranged, and only be positioned at the scale of lighting the light beam scope and lighted (see figure 7).Like this, both make things convenient for reading, and can avoid display effect excessively in disorder again.Also have an additional benefit when rule also is 10 multiple: the quantity that user number counting is lighted scale in the light beam just can directly obtain the tens of departure; Count the units that scale lighting elements number in addition can obtain departure again.The two combination can obtain complete departure numerical value.
For fear of light end points and cursor when adjacent or overlapping the user be difficult to differentiate the definite position that shows end points, the point that the present invention lights cursor flicker is empty than some variations take place thereupon, with expression respectively light end points away from, approaching, overlapping and surpass a certain cursor.Light the light-emitting component (see figure 4) of not lighting in addition between end points and the cursor away from being meant.Light the adjacent (see figure 5) of end points near being meant with cursor.Overlapping referring to lighted end points and is positioned at (see figure 6) on the cursor just.Surpass only appearance when overproof, light end points in this case and surpassed the cursor (see figure 3).
Cursor flicker dutycycle can recently realize with the number of times of the output that resets by changing cursor display position position.The time that number of times determined of the set and the output that resets all must persist the time greater than human eye vision, to form visual flickering.When light end points away from or when surpassing a certain cursor, the set output and the number of times of the output that resets are equated, point of scintillation is empty than being 0.5; When lighting end points near a certain cursor, make the number of times of the number of times of set output less than the output that resets, the flicker dutycycle is less than 0.5; When lighting terminal point and be overlapped in a certain cursor, make the number of times of the number of times of set output greater than the output that resets, its flicker dutycycle is greater than 0.5.In program, be easy to utilize counter to realize the different variations of the set output and the output number of times that resets.
